Not using advertising in a blog is a good thing. Often the profit margin is not as big as it once was so people take the ads off until the site gets the necessary links and traffic. Not having ads can be especially critical if your blog serves a traffic purpose like driving traffic to your YouTube videos that pay you through the shares program. In that case the videos have ads but this keeps adds away from your blog's content or navigation. On the other hand at the end of the day I have abandoned more sites for the simple reason that they do not make much money. Because of this I now make sites online on subjects guaranteed to pay me for my time and energy. What is your opinion on this subject?
